North Korea is once again seeking to stir up a crisis: testing several surface-to-ship missiles March 28 in the West Sea, warning that U.S. insistence on disclosure of its uranium program (rather than just its plutonium program) could stall or end progress on the dismantling of North Korea's already-declared nuclear facilities, and kicking South Korean government officials out of the Kaesong joint economic zone . But so far, no one is biting Pyongyang's crisis bait. The North Korean leadership might be learning the limits of its crisis diplomacy. For nearly two decades (since the collapse of its Cold War patron system), North Korea has survived well beyond the expectations of many analysts. In fact, the country and its regime haven't simply survived.
